Abstract
The utility model discloses a mechanical seal lithium cell is provided with the inner shell in its shell, and during the inner shell was arranged in to the core, be equipped with an insulating support ring between inner shell top and the upper cover, the positive pole lead wire of core was a stainless steel foil who links to each other with the positive pole, and this stainless steel foil passes insulating support ring and welds the central point that puts the department at the upper cover. The advantages are simple structure, easy manufacture, good sealing effect and good product performance.
Description
Technical field
The utility model relates to a kind of lithium battery, belongs to technical field of chemical power.
Background technology
Existing a kind of model is the compact lithium cell of DL1/3N, the version that adopts is the mechanical encapsulation of housing and cover assembly, loam cake central authorities are welded with a stainless steel stem, the galvanic anode currect collecting net is around being welded on the stem, this stem height overall just in time is the battery inside wall height, and it plays the effect of supporting loam cake.This structure is to the manufacture process requirement height, and the stainless steel stem that welds with loam cake need weld very firmly, also requires solder joint little, is difficult for realizing; In addition, metal lithium bands (being anode) need prolong and is pressed on the currect collecting net, be welded on the stem again, and then and barrier film, negative electrode reel together, technology is very numerous and diverse.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, provides a kind of manufacture craft simple, and the mechanical seal lithium battery of good sealing effect.
Realize the utility model purpose mechanical seal lithium battery, be tightly connected by shell and loam cake mechanical type, inside has by anode, anode tap, negative electrode, cathode leg, the formations such as core body that barrier film constitutes, its design feature is: be provided with inner casing in the shell, core body places inner casing, be provided with an insulation support ring between inner casing top and the loam cake, the anode tap of core body is a stainless steel foil that links to each other with anode, and this stainless steel foil passes the center position that the insulation support ring is welded on loam cake.
The utility model utilizes inner casing and support ring to finish loam cake and supports, by one directly with core body in the stainless steel that joins of anode moor and serve as anode tap, the stainless steel stem of loam cake bottom center and the currect collecting net of metal lithium bands have been cancelled, manufacture craft is simplified, the anode tap of being served as by stainless steel foil can touch weldering with loam cake more in large area, makes its welding sequence simple; And core body need not to prolong the pressure currect collecting net before reeling, the welding lead post, and it is convenient and easy that core body is reeled.
Described cathode leg flange can be welded on the outer wall of inner casing, inner casing and shell interference fit are installed together.The benefit of doing like this is to reduce the internal resistance of cell, enhances product performance.
For guaranteeing good seal, can carry out secondary at described shell faucal coating one deck fluid sealant and seal.Make casing deformation little and reach good sealing effectiveness.
Following insulating trip is arranged at outer casing inner wall bottom, and interior shell opener down, the inwall top is equipped with insulating trip.Can guarantee the insulation of battery two interpolars.
Compared with prior art, the utility model has the advantages that simple in structurely, make easily good sealing effect, good product performance.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Accompanying drawing is the half section structural representation of the utility model embodiment
Embodiment
Referring to Fig. 5～6, this mechanical seal lithium battery is connected with loam cake 1 mechanical sealing by shell 11, inside has by anode 6, anode tap 5, negative electrode 7, cathode leg 8, the formations such as core body that barrier film 9 constitutes are provided with inner casing 3 in the shell 11, core body places inner casing 3, be provided with an insulation support ring 2 between inner casing 3 tops and the loam cake 1, the anode tap 5 of core body is a stainless steel foil 5 that links to each other with anode 6, and this stainless steel foil 5 passes the center position that insulation support ring 2 is welded on loam cake 1.
In the present embodiment:
Cathode leg 8 flange are welded on the outer wall of inner casing 3, and inner casing 3 is installed together with shell 11 interference fit.
Shell 11 faucals are coated with one deck fluid sealant.
Following insulating trip 10 is arranged at outer casing inner wall bottom, and interior shell opener down, the inwall top is equipped with insulating trip 4.The manufacturing process of present embodiment is: place anode 6, barrier film 9 and negative electrode 7 on request and reel, the core body of winding is put into the inner casing 3 of loading onto insulating trip 4, draw anode tap 5 and cathode leg 8.Anode tap 5 is stretching, put support ring 2, subsequently anode tap 5 is welded on the center of loam cake 1.The inner casing 3 that core body is housed soaked to put into after good in electric liquid have the assembling that shell 11 that following insulating trip 10 and oral area scribble fluid sealant 12 is promptly finished this lithium battery.The battery that assembles is put into sealing die once seal, purpose mainly is to close up; Battery after will once sealing again takes out, and puts into the secondary sealing die and carries out secondary and seal, and seals on request to get final product.
